Interest on checking accounts is taxable income

Any interest your bank pays you on a checking account counts as ordinary income on your federal tax return. The IRS treats it the same way it treats wages or freelance earnings — you owe income tax on the full amount. Your bank will report this interest to you and to the IRS on a Form 1099-INT if the total reaches $10 or more in a calendar year.

The tax you owe depends on your overall income and tax bracket. If you earn $500 in checking account interest and you're in the 22% federal tax bracket, you'll owe roughly $110 in federal income tax on that interest alone (before state taxes, which vary by location). The interest is added to your other income when you file, so it can push you into a higher bracket if you're close to a threshold.

Most checking accounts earn little or no interest, so this is rarely a large tax bill. But high-yield checking accounts — which some online banks and credit unions offer — can generate several hundred dollars per year in interest, making the tax impact real enough to plan for.

Key Takeaways

  • You must report all checking account interest as income on your federal tax return, regardless of the amount.
  • Your bank sends you a Form 1099-INT if interest reaches $10 or more in a year, and also sends a copy to the IRS.
  • The tax you owe on the interest depends on your tax bracket and is added to your other income for the year.
  • State and local income taxes also apply to checking account interest in most states, on top of federal tax.
  • High-yield checking accounts can generate enough interest to create a meaningful tax liability, so factor that into your planning.

When your bank reports interest to the IRS

Banks and credit unions are required to file a Form 1099-INT with the IRS for each account holder who earns $10 or more in interest during a calendar year. You receive a copy of this form by January 31 of the following year. The form shows the account number, the total interest paid, and sometimes a breakdown by type (ordinary interest versus U.S. Savings Bond interest).

If you earn less than $10 in interest, your bank may not send you a 1099-INT, but you still owe tax on that interest. You are responsible for reporting it yourself on your return. The IRS has records of what large banks report, so underreporting interest is a common audit trigger.

Keep your 1099-INT forms and any statements showing interest deposits. If the amount on the form is wrong — for example, if interest was credited twice or if you closed the account mid-year — contact your bank to request a corrected form (Form 1099-INT with a "Corrected" box checked).

How to report checking account interest on your tax return

When you file your federal return, you report interest income on Schedule 1 (Form 1040), line 8, under "Interest." If you use tax software, it will prompt you to enter the amount from your 1099-INT. If you file by hand, write the total interest from all your accounts on that line.

If you have multiple accounts at different banks, add up all the interest from all the 1099-INT forms you received and report the total on that single line. You do not file separate schedules for each account.

Some tax software will import 1099-INT data directly from your bank if you connect your account, which reduces the chance of entry errors. If you file with a tax professional, bring all your 1099-INT forms with you.

State and local taxes on checking account interest

Most states tax interest income the same way the federal government does. If you live in a state with an income tax, you will owe state tax on your checking account interest as well. The rate varies by state — from roughly 3% to over 13% depending on your income and location.

A few states do not tax interest income at all. These include Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming. If you live in one of these states, you owe only federal tax on your checking account interest. New Hampshire and Tennessee tax only interest and dividends, not wages.

Some cities also impose local income taxes. New York City, for example, taxes interest at rates up to 3.876% on top of state and federal tax. Check your state and local tax authority websites to confirm your rates.

Why high-yield checking accounts create a larger tax bill

Traditional checking accounts at large banks pay little to no interest — often 0.01% APY or less. A $10,000 balance earns roughly $1 per year, which is below the $10 reporting threshold and creates no meaningful tax burden.

High-yield checking accounts, offered mainly by online banks and some credit unions, pay 4% to 5% APY (rates change frequently). The same $10,000 earns $400 to $500 per year. At a 22% federal tax rate plus a typical state rate of 5%, you owe roughly $135 in combined taxes on that interest.

This is still a net gain — you keep the after-tax interest — but it is important to factor the tax cost into your decision. If you're comparing a high-yield checking account to a regular savings account, remember that the interest on both is taxable. The higher rate means more interest, but also a larger tax bill.

Interest on joint accounts and how it affects your taxes

If you own a checking account jointly with another person, the interest belongs to both of you unless your account agreement specifies otherwise. The bank will report the full interest amount on a single 1099-INT, usually in the name of the first account holder listed.

You and the other account holder must decide how to split the interest for tax purposes. If you contributed 60% of the funds and the other person contributed 40%, you would typically report 60% of the interest on your return and the other person reports 40%. Keep records of who contributed what and how you split the interest, in case the IRS asks.

If the bank reports all the interest under one person's name and Social Security number, that person should file an amended return or attach a note to their return explaining the split. The other account holder should also report their share on their return. Mismatches between what the bank reports and what you report can trigger IRS notices.

What to do if you did not receive a 1099-INT

If you earned $10 or more in interest but did not receive a 1099-INT by February 15, contact your bank and ask them to send it. Banks sometimes mail them late or to an outdated address. Request a duplicate copy or ask them to email it to you.

If your bank says they did not send one because interest fell below $10, ask for a statement showing the exact amount. You still owe tax on it even if no form was issued. Report the amount on your return based on your account statements.

If you cannot get a 1099-INT from your bank, use your own account statements to calculate the interest earned and report it on your return. Keep copies of the statements in case you are audited. The IRS may have a record of what the bank reported, so it is better to report the interest yourself than to omit it.

Frequently Asked Questions

Do I have to pay taxes on interest if I earned less than $10?

Yes. The $10 threshold only determines whether your bank sends you a 1099-INT form. You are legally required to report all interest income, no matter how small. If you earned $5 in interest, you owe tax on that $5.

Can I deduct anything against the interest income I earned?

No. Interest income is reported as-is on your tax return. You cannot deduct account fees, overdraft charges, or other banking costs against it. Those expenses are generally not deductible for individual taxpayers.

What if the 1099-INT my bank sent has the wrong amount?

Contact your bank immediately and ask them to issue a corrected 1099-INT. They will send you a new form marked "Corrected" and will also send a corrected copy to the IRS. File your tax return using the corrected amount. If you already filed, you may need to file an amended return.

Is interest from a money market account taxed differently than checking account interest?

No. Money market accounts, savings accounts, and checking accounts are all taxed the same way — as ordinary income. The type of account does not matter; only the interest amount does.

Do I owe self-employment tax on checking account interest?

No. Self-employment tax applies only to income from self-employment or a business. Interest from a checking account is passive income and is not subject to self-employment tax, only regular income tax.
